BYOB support for Fetch

Category: Network / Connectivity
Type: Chromium catches up
Status: Enabled by default (Chrome 116)
Intent stage: None

Summary

Makes Response.body be a readable byte stream instead of a "default" readable stream. This enables it to be used with bring-your-own-buffer (BYOB) readers, reducing garbage collection overhead and copies.
